SQL & PL/SQL

Hi Guys,

How do I remove a comma at the end of an output of a function that I've decoded?

Ex:

ID Category

1 Law,

2 Government, Law,

3 Science, Health, Finance,

P.S.

The category is basically a bunch of concatenated fields from a function to return if a person has law, govt, etc experienced.

Thanks.
